摘要:
In a calibration data input process, a carriage 5 is moved toward an ink sensor 19 to a prescribed position while the ink sensor 19 detecting levels of reflected light. Then the amount of reflected light is read for over a range wider than the width of the carriage 5 including a theoretical detecting position P2. An actual detecting position P1 is found based on the level of reflected light. The difference between the theoretical detecting position P2 and the actual detecting position P1 is calculated and is stored as the calibration value &agr; in a first calibration data memory M1. Accordingly, the actual detecting position P1 is set as P2±&agr;. The calibration value &agr; is used in a calibration process to calibrate the detecting position, so that the level of reflected light can be detected with accuracy.

An image input-output apparatus includes a housing which is internally provided with a common transfer path. Further, the housing internally incorporates a transfer mechanism for selectively transferring a document and a recording paper along the common transfer path, a combination of an image reading light source and an image sensor for optically reading an image of the document moving along the common transfer path, and a printing unit for printing an image on the recording paper moving along the common transfer path. The width of the recording paper may be detected by a combination of a width detecting light source and the image sensor.

An image recording apparatus includes a recording head having a plurality of element arrays in a scanning direction, a driving device, a transporting mechanism and a selecting device. Each element array includes a plurality of recording elements arranged with a predetermined spacing in a direction approximately perpendicular to the scanning direction. The driving device drives the recording elements of the recording head. The transporting mechanism moves the recording head relative to the recording medium in the direction perpendicular to the scanning direction. The selecting device selects between a first recording mode for performing the recording operation with high resolution and high precision and a second recording mode for performing the recording operation with high speed. When the first mode is selected, the recording head moves to record additional dot lines formed by the recording elements of each element array between initial dot lines formed by the same. When the second recording mode is selected, more element arrays are used than in the first recording mode to perform the high speed recording operation. Further, the first mode reduces effects caused by unevenness of the space between each of the element arrays and fluctuations in scanning speed.

The shift register 43Y is written with four bits of data for recording dots of yellow color, the shift register 43M is written with four bits of data for recording dots of magenta color, the shift register 43C is written with four bits of data for recording dots of cyan color, and the shift register 43Bk is written with four bits of data for recording dots of black color. The recording head 29 is scanned relative to the recording paper 33 in dot intervals D in a scanning direction. In the recording head 29, the recording units 30Y, 30M, 30C, and 30Bk for recording the four colors are aligned in the scanning direction with an interval P equal to a sum of one dot interval D and a multiple of four dot intervals 4D. With this arrangement, the shift registers 43 are supplied with the four bits of data at timings shifted from one another by an amount corresponding to one recording timing period T. Each recording unit will select and record one bit of data out of the four bits of data stored in the corresponding shift register. Positions in the shift registers, from which the respective recording units select their data, are shifted from one another. Accordingly, data processes for the four colors are distributed uniformly amongst all the recording timings.
